Fig. 12 is a view partly in elevation and partly in section taken on the irregular line 12`-"12ofFi v.11. v y 4 y The inop head includes upperand lower yoke-'like members 1 2 and 13, respectively, the lat-ter of which is provided witha tubular shank 14 rigidly secured to the transverse elevation of the mop-holdportion ofisaid lower head member at the center thereof.` vThese headinembers 12 and 13 are slidably mounted the one uponv the other by having the transverse por-tion of the" upper head 12 extended Athrougha pair of aligned slots inthe shank 14 for sliding movement 'longitudinally thereof. Said head members 12 andi?) are further `slidably 4 connected .bymaking the prongs of the lower head member channel-shaped in cross section and slidablymounting the prongs kof the upper head member therein. These channeli shaped prongs oi the lower mop member 13 also greatly strengthens the mopV head. l

A long mop handle 17, only a portion, of

which is shown, has its lower end portion iitted into the shank 1 4Y and rigidly secured thereto with its lowerend axially spaced from theupper head member In addi'- tion to the sliding eng'fagement of the transverse portion of' the upper head member 12 withv the shank 14;, said member and shank are further slidably connected and the shank 'braced from the upper head member 12 byv a collar 18 slidably mounted on the shank 14 and a pair .ofv arms 19 that rigidly'connect said collar to the outer "ends of the transverseportion of the upper head member 12.

A coiled spring 2O is mounted within the tubular shank 14 and is compressed between the upper head'nieii'iber and the lower end of the handle 17 and yieldingly draws the transverse portions of the head members 12 and 13 toward eachother. AV relatively long flat plate rigidly secured to the upper head member 12 extends into the spring 20 and cooperates withsaid member to afford a seat 21 for said spring. Carried by the prongs of the upper and lower head members 12 and 13 are upper ai'id'lower leo-operatingV wringing rolls 22 and V23, respectively. The lowen rolls 23 also-afford a holder fora mopm, as will presently appear. Said upper 1'01122 is provided with headed trunnions 24 which extend through longitudinally extendedy slots 25 in the prongs of the lower head memberll head member 12,

"he rou 23 is tubular and has] farmed `therein a wide longitiidinallyy extendedvslot members 27 that are looseJ siiidbirollfin apposite dirtion's fom 'eensildr 1e' diS- tance from the slot 26 whereby said roll may and are journaled `in the prongs of the upper y mon rotation. Said core 28 at its ends en-, vgages the opposing faces of the prong of the lower head member 13, which are extended outward of the ends of the prongs of the upper head member 12, :and holdl the same laterally spaced.

The lower roll 23 is lrotated in one direction by a hand crank 30 to wind the mop a: thereon and wring the same between the two rolls 22 and 23, and then rotated in a reverse direction to unwind said mop :trom

'the roll 23 after the same has'been wrung.

This hand crank 30 is provided with a long spindle 31 which extends through the core 2S and the prongs of the lower head member 13. Said spindle 31 except at its ends` is square in cross section and snugly tits in the core 28 to connect said core and hence the roll 23.150 the spindle 31 for common rotation. Theends of the spindle 31 are round and journaled in the prongs of the lower head member 13. The outer ends oi' the spindle 31 project outward of the respective prong of the lower head member 13 and has applied thereto a washer 32 and a pin. 33 which, together with the arm of the hand crank 30, holds said spindle against endwise movement inn the prongs of said head member and also holdsaid prongs against lateral spreading movement.

The hand-piece 34 of the hand crank 3() has a tubular body on the outer end of which is a knob 35. The'body member of the handpiece 34 is mounted in the outer end of the arm of said crank for endwise sliding movement transversely thereof and is held from turning therein by a key-acting spring latch 36 attached to said member and extending 'into a key way 37m said arm. An annular shoulder 38 on the inner end of the body of the hand-piece 34 is arranged to engage the inner face of the arm of the hand crank 30 Aandlimit the 'outward endwise movement of said `hand-piece. The latch 3G when the hand-piece 34 is in its outermost position and stopped by the shoulder 38 engages the outer face of the arm of saidhand crank and holds the same against inward endwise movement.

Vhen the device is used as a mop, the hand cijank 30 is'positioned 'directlylover the adjacent prongsof the head members 12 and 13 and the body of the hand-piece moved into the tubular transverse portion of the head member 12 which afords a lock seat 39 therefor. The frictional engagement with the spring latch 36 and seat 39 releasably hold the body of the hand-piece 34 in said seat.

Formed in the outer end ofthe arm of the hand crank 30 and the adjacent arm 19 are depressions 40 and 41, respectively, arranged to receive the thumb of the operators hand, when holding the knob 35, to assist in positioning said hand crank with the body of its hand-piece 34 aligned with the seat 39. When the body of the hand-piece 34 is in its seat 39, the hand crank 3() is held thereby against swinging movement, the head members 12 and 13 are held against sliding movement in respect to each other and the roll 23 is held from turning.

Vhen the device is used as a wringer, the

same is held by the operator, as indicated by the hands y in Fig. 9. Corrugations are formed in the under surface of the transverse portion of the head member 13 to afford linger holes 42. A knob 43 like the knob 35 is secured to the head member 12 at the opposite side from the hand crank 30 to give the device a symmetrical appearance.

The mop illustrated is of the knitted type and comprises inner and outer plies folded upon themselves. Said mo m is attached to the roll 23 by having the lblded portion of its inner ply inserted into the mop-holding roll 23 through the slot 26 and the core 28 inserted through the looped portion of said mncr ply. The longitudinal edge portions of the mop-holding roll 23 -at the slot 26 are then pressed toward each other to pinch the folded inner plyol:l the mop a: therebetween and it is important to note that said edge portions are radially offset from each other, as best shown in Figs. 3, 7 and 10. The purpose ot' radially olfsettingthe longitudinal edge portions ot the mop-holding roll 23 is to cause the mop a: to wind thereon concentric with said roll to eliminate any ridges or bumps in the mop n; that would interfere with the wringing thereof. Outward of the slot 26 the two plies of the mop a: are stitched or otherwise fastened together, as indicated at e. The mop a: completely covers the roll 23 se thatl pressure may be applied thereto so as to rub that portion of the mop directly under the roll 23 on the floor. u n To wring the mop a.' the hand-piece 34 1s drawn out ot its seat 39 and then the hand crank 30 operated to turn the roll 23 and wind the mop :u thereon` until the free end portion of said mop passes under the roll 23 and drops down. The direction of movement ot' the hand crank 30 is then reversed and operated to unwind the mop a. from the roll 23.
